When I was like 13, my bed I've had for ages broke, so I was sleeping on
the floor until the next week when I was able to get a new one. I was
sleeping with my feet facing my bedroom door so if I sat up, I'd be
staring at the door.

I woke up in the middle of the night, around 2:30-ish to scratching at
my bedroom door. I sat up and stared at my door and scratching
intensified. Then the door suddenly slammed open and closed almost
immediately, the neon green glow of my alarm clock showed nothing behind
the door when it opened and I was scared shitless. I do have a dog, but
she'd have to go through my parents bedroom door, and the stairway door,
so not possible.

When I was even younger, I'd often get this feeling, of not being quite
myself I guess you can say, when I would be trying to sleep and my bed
would start to shake, not softly, but not violently either. I would also
hear voices that sounded like it was coming from a walkey talkey or
something and foot steps going up the stairs.

Before anyone claims "Oh this was sleep paralysis." It wasn't. I know
what sleep paralysis is, and I've had it twice, those times were not it
since I was able to move around and talk
